Twofold

Twofold is a liquidity protocol on Robinhood Chain (chain id 4663). It runs Uniswap's DualPool contracts, a Uniswap v4 hook design in which the idle side of a liquidity pool is deposited into an ERC-4626 lending vault while the pool remains open for swaps. A liquidity provider in a Twofold pool earns swap fees from the pool and lending yield from the vault on the same deposit.

The protocol deploys Uniswap's DualPoolHook and AllowlistedFactory without modification; the deployed bytecode matches the audited upstream source. Twofold adds a controller, a pool registry, a vault allowlist and a staking vault around those contracts. As of September 2026 the registry lists 24 pools, each pairing the USDG stablecoin against another asset on Robinhood Chain: WETH, TWO, and tokenized equities and funds such as SPY, QQQ, NVDA, AAPL, TSLA, GOOGL, MSFT, META and AMZN. The USDG leg of every pool is routed to a Steakhouse USDG vault built on Morpho Vaults V2. USDG is the only asset on the chain with an eligible vault, so the non-USDG side of each pool earns swap fees only.

TWO is the protocol's token, an ERC-20 with a fixed supply of 1,000,000,000 and no transfer tax.
